Metric wrenches cover most of the fasteners you'll encounter on a modern bicycle, and Park Tool's MW-SET.2 puts the seven most common sizes in one organized roll-up pouch. The set spans 6mm through 17mm, which handles everything from brake caliper mounting bolts to pedal flats to the larger fasteners on stems and headset components. Each wrench uses a combination design with an open end on one side and a box end on the other, giving you two engagement options depending on clearance and how much torque you need to apply.

The wrenches themselves are drop-forged from chrome vanadium steel, then chrome-plated for corrosion resistance. This isn't the soft steel you find in bargain tool sets that rounds off after a few uses on stubborn bolts. The box ends use a 12-point design that allows 30-degree repositioning in tight spaces, while the open ends provide quick access when you have room to swing. Forging orients the steel's grain structure along the length of the tool, which matters when you're putting serious leverage on a seized fastener.

Park Tool designed this set specifically for bicycle applications, which shows in the size selection. You get 6mm for smaller component bolts, 8mm and 9mm for brake and derailleur mounting, 10mm for axle nuts and various hardware, then 15mm for pedals and the larger 16mm and 17mm sizes for headset locknuts and certain hub configurations. The roll-up pouch keeps everything organized in your toolbox or shop apron without the sizes getting scattered across your workbench.... Read More
